It's (almost) solved! I have added the following to /etc/default/bluetooth:
HIDD_OPTIONS="-i hci0 --connect 00:07:61:3F:DA:41 --connect 00:07:61:48:71:DE --master --server" 00:07:61 is Logitech, 3F:DA:41 is the keyboard; 48:71:DE is the mouse. I rebooted. It's my impression that the keyboard doesn't work in grub. During the boot process, the LCD on the keyboard asks for a password. When kdm comes up, both mouse and keyboard are working. I can also send pictures to/from the phone. This leaves only one minor issue to investigate/solve: why doesn't the keyboard work in grub? I don't consider entering a password on the keyboard a problem. I kinda like the idea that you have to enter a password on the physical device you use to enter a password on the computer. That's extra security ;-) -- Bluetooth Mouse and Keyboard Broken in Dapper/Edgy/Feisty https://launchpad.net/bugs/32415 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
